      It’s very subjective. You can read more about it by searching around, but the prevailing definition means people who had more severe reactions to the infection than the average patient, which almost unanimously means a severe and prolonged inflammatory response.

      What they are finding more and more is that this specific virus triggers undiagnosed or dormant autoimmune responses in patients. If you’re familiar with Rheumatism at all, imagine a massive reaction to, say, twisting your ankle, but it goes out of control and causes swelling all over your body including your brain, lungs, heart, and renal system. This is actually what killed the most patients pre-vaccination.

      The full body assault of an inflammatory response just makes the body unable to cope, and things start shutting down. It can kill children and older people very easily if you can’t get it under control. Many succumbed to Pneumonia, but those that lived had damage to their major internal organs from the inflammatory response. You can also see some had been using the term “Walking COVID”, meaning people who had cleared the infection, but had long term sustained symptoms similar to Emphysema. They’ve since just moved on to calling everything “Long COVID”. Some people recover, some people don’t.

      This study finally identified the specific damage and detection to brain activity.

        People don’t get it. The inflammatory process can do these sort of thing to any organ or system, or parts of them.

        People got a thing called COVID Toe. This is where you and every person already has some fungus that live on their feet and which gets into the skin and toenails. Maybe you have a little yellowing of the toenails or you’re just “prone to athletes foot.”

        Then you get COVID and suddenly your immune system is working overtime. The fungus starts to multiply faster and spreads more aggressively. Your toes start to get itchy and red, more than usual. They swell. They yellow. Then they start to crack and ooze, possibly requiring surgical debridement or in the most severe cases, such as where the patient already had diabetes affecting their peripheral nerves, amputation of the foot to prevent necrosis and sepsis.

          Interesting. I had an increase in fungal presence, but I figured it was excessive boot usage due to starting motorcycle riding 5 months after my first covid infection. It clear near winter for the most part but I wonder if I just hadn’t noticed the initial spread.

              It’s absolutely ridiculous how hard the school systems make it to get on a bus route.

              You basically have to stay at the same residence and at the same school for their entire education. Even just moving within the district and they use it as an excuse to “put you on a wait list”.

              Add in the shortage of drivers (who wants that job) and any excuse they can use to change boundaries or cut a route.

              It’s like the fucking DMV on steroids.

        Airports and planes see a lot of traffic from all over the world constantly rotating through. With some variation depending on the size of the city and your personal schedule, you’re running into more of the same people on normal public transport.

          And you’re in very close proximity for a very long time. I don’t know how HVAC works on an aircraft but I assume there’s a large amount of recirculation.

          I was on buses and trains this morning. They weren’t nearly as crowded, the trips were a lot shorter, the air moved around at every stop, and like you said, they’re all pretty local, so low risk of someone importing weird diseases. At least on the subways, you should still wear a mask if only because of the air quality. There’s a lot of brake dust floating around.

            The filtration system on an airplane makes it one of the safer places to be for almost any airborne infection. The airport itself is much more dangerous, longer flights notwithstanding.

              Surgical/cloth are pretty much useless for COVID. N95s buy you temporary protection unless you’ve got the special face fittings needed to actually seal your face. It depends on the environment you’re in but the worst case scenarios (like enclosed spaces without high airflow), the last study I saw was on the Delta variant and they said about 15 minutes if both parties are masked. It does get better from there though, with good ventilation you might have a few hours, and being outdoors you’re actually pretty safe.

        Chronic fatigue syndrome.

        It’s another one like long covid where so much of the medical community thinks it’s all in people’s heads and not real, but unlike long covid it’s less prevalent and thus studied less. We still don’t know what it is.

        There’s even some hopes that figuring out long covid might lead to new ways to look into what cfs really is.

        CFS is a syndrome rather than a disease because, until recently, it only presented as symptoms instead of as an identifiable problem with a person. I know that a some people who get diagnosed for CFS get later diagnoses as neurological disorders like multiple sclerosis.

        It sounds like the more powerful MRI scanners are seeing inflammation in the rest of those suffering from CFS.

        That would mean CFS is a lifelong degenerative condition.

          Hey I’m a researcher who works on ME (in the past called CFS).

          ME/CFS is currently classified as a disease/biological illness according to the CDC.

          ME is a disease state in itself. We don’t know much about it, but it can’t be explained by other diagnoses, as the defining factor, neuro-immune abnormalities including immune activation showing up post exertion is unique to it. You’re completely right that we don’t yet have a reliable biomarker. We have a test that differentiates from healthy controls, but it was discontinued for ethical reasons because conducting the test leads to a sometimes permanent worsening of the illness.

          In the past it’s been mixed up and jumbled a lot, but the picture is getting clearer.

          There have been a few case reports of degenerative forms of the illness. But in general it takes a more classical relapsing remitting pattern. Although even in less bad stages some patients are severely functionally disabled, even bedridden and tubefed. It has a really wide range of severities with the least severely affected able to work part time and walk and travel, while the most severe might not even be able to communicate.

          this is the extent of what I knew about CFS, I never heard of ME, I thought CFE was still a collection of symptoms that didn’t even indicate a single underlying syndrome.

          I like the progress, clearly seeing brain stem inflammation sounds like comic book talk from 20 years ago.

          they’re going to see inflamed dendrites next.

          oh but isn’t clogged dendrites how they identify multiple sclerosis already?

          clearly I have to read more about this. catch up a bit.

          thanks for the explanation.

            A collection of symptoms is a syndrome. Once there is a known definite cause, reclassification as a disease can take place. Lay misuse of the terms and reluctance to adopt updated designations have aided in a loss of distinction in what they refer to.

            There is something else entirely to be said for how quickly one can progress from the disbelief of a particular diagnosis as anything beyond a punchline to descanting over the marvels of modern medicine as they relate to futher study of the mechanisms. If nothing else, it’s a great reminder of how much information is available to us on a whim.

              it is, and they can take pictures of the inflamed dendrites and axons showing where they’re clogged, so I was wondering how much smaller these substructures in the brain stem are than dendrites and axons that neurons travel through, which are pretty freaking small and we’ve had pictures of for at least a couple decades now.

              oh or maybe those were microscope slides and they’re saying now we can microscopically look at this stuff without having to cut into it.

        Lifelong disease usually triggered by viral infections. Very functionally disabling.

        Known immune abnormalities which seem to affect the brain and mitochondria. I think @Neurologist@mander.xyz is specialised in it.

        Also “chronic fatigue syndrome” was the name back when it was classified as psychological. Now that it’s classified as neuroimmune the name has been changed to Myalgic Encephalomyelitsis (ME) (Or ME/CFS).

        As usual though for a medium quality source like ScienceAlert, the article is written by someone who has no specialisation in Long COVID/ME, or even medicine. So there’s a bit of oversimplification and overstating findings from one study in that article. Very few researchers think it’s a brain injury. Most think the immune system has been compromised (with some deficiencies and abnormalities) and it’s affecting the brain in unknown ways (hence the abnormalities found. It’s weird though because the immune system problems seem to cause some immunodeficiencies but also autoimmune reactions. They’ll need to be quite a bit more studies before we get a clear picture.

          Couldn’t have said it better. And yes, science journalism often is basically repeating and dumbing down what a study says, but in science, and especially in medicine, a lot of studies tend to be wrong, make false assumptions, or overstate their findings, while journalists tend to take them for their word. There’s a reason you hear of a new cancer treatment in the news every other week but few actually make it past FDA approval.

            Seems like it generally just gets triggered by a viral infection, but obviously it’s hard to find conclusive evidence for that as people get viral infections all the time and usually recover fine. In a way COVID was a useful ‘experiment’ where we got a lot of cases of people getting long COVID right after a confirmed infection (because everyone was getting tested, which you typically wouldn’t do for your average viral infection).

              Yeah. Atleast 50% report an onset right after a viral infection. And it’s not impossible to assume the other 50% were caused by viral infections too but the patient didn’t make the connection. Obviously we don’t really know yet.

                Yeah, would be hard to prove unless people started routinely testing themselves for a broad array of viruses every time they fall ill.

                But hopefully with the influx of long COVID patients more research will be done, and people with CFS, fibromyalgia and similar diseases will at least be believed, because all of those are typically dismissed because you can’t really see it.

    Using high-resolution scanners, researchers at the Universities of Cambridge and Oxford have shown microscopic, structural abnormalities in the brainstems of those recovering from COVID-19.

    Signs of brain inflammation were present up to 18 months after first contracting the SARS-CoV-2 virus.

    […]

    In living brains of those with long COVID, however, conventional MRI studies have shown no structural abnormalities in the brainstem.

    Do these people not proof-read their own articles?
